The range owner has every right to determine who and what uses his range. I personally can't stand to share a range with guys that show up with AKs and a bucket of cheap ammo to see how fast they can shoot. Allowing some of these guys to dominate the range can cause other shooters to leave the range. Everyone has the right to ownn and shoot whatever they want, I support thier rights, but the range owner has rights also. There is a time and place for everything.
